Mather, who won the 2006 Nobel Prize in Physics for his precise measurements of cosmic microwave background radiation using the Cosmic Background Explorer satellite, currently leads the science team for the James Webb Space Telescope, which is scheduled to launch in 2018. His research focuses on infrared astronomy and cosmology.

Mather is a member of the American Astronomical Society, American Physical Society, National Academy of Sciences, and the American Institute of Aeronautics and Astronautics.
